Abstract: A method of determining a concentration of a gas in a sample and/or of the composition of a gas by means of a spectrometer includes measuring an absorption signal of the gas as a function of the wavelength. The wavelength substantially continuously runs through a wavelength range and is superimposed by a harmonic wavelength modulation, wherein the influence of the wavelength modulation on the absorption signal via the light source modulation properties and the detection properties of the spectrometer is dependent on the device properties of the respective spectrometer. The method includes converting the absorption signal into at least one first derivative signal; deriving a gas concentration measurement parameter from the first derivative signal; determining the concentration and/or composition of the gas from at least the gas concentration measurement parameter and from a calibration function compensating for influences of state variables of the gas and of the spectrometer properties.

Abstract: If the specific gas concentration is relatively high, controller sets 0 as the modulation amplitude in a modulation amplitude controlling voltage generator for frequency modulation of laser light, controls a switching unit to select the output of a second ADC, and causes a computation unit to compute according to the direct absorption detection method to calculate the water molecule volume concentration. If the specific gas concentration is relatively low, the modulation amplitude is set to A, not 0, controls switching unit to select the output of a first ADC, which digitizes a synchronized detection signal, and causes the computation unit to compute according to the harmonic synchronous detection method to calculate the water molecule volume concentration. The concentration calculated using either of the methods is compared against a threshold value, and if decided that an accurate result cannot be obtained, the method is switched as the measurements are continuously executed.

Abstract: A system and method for spectroscopic detection of loss in a resonator cavity is disclosed. The system can include a number of components. A tunable laser source can generate a laser beam. A frequency locking system can lock the frequency of the laser beam to a resonance of the resonator cavity or lock the length of the cavity to the frequency of the laser beam. The first modulation element can modulate the laser beam at a first modulation frequency to generate a modulated laser beam. The input coupler can direct the modulated laser beam into the resonator cavity. The first directing element can direct a first portion of light reflected from the input coupler to a first photodetector. The first demodulator can demodulate the first modulation signal to generate a first error signal which is a function of the loss in the resonator cavity.

Abstract: The invention is a system and method of detecting a concentration of an element in a soil sample wherein an opening or slot is formed in a container that supports a soil sample that was extracted from the ground whereupon at least a length of the soil sample is exposed via the opening. At each of a plurality of points along the exposed length thereof, the soil sample is ablated whereupon a plasma is formed that emits light characteristic of the elemental composition of the ablated soil sample. Each instance of emitted light is separated according to its wavelength and for at least one of the wavelengths a corresponding data value related to the intensity of the light is determined. As a function of each data value a concentration of an element at the corresponding point along the length of the soil core sample is determined.
